WebOct 26, 2024 · Quoting your uncertainty in the units of the original measurement – for example, 1.2 ± 0.1 g or 3.4 ± 0.2 cm – gives the “absolute” uncertainty. In other words, … WebThe ability of a device to measure an exact or accurate value is called accuracy. The proximity or closeness of two or more measurements to each other is referred to as the precision of a material or substance. The uncertainty of a measured value is an interval around that value, so each repetition of the measurement produces a new result which ...
